One-Time Credits vs Monthly Subscription: The Real Cost
Competitor prices checked October 2026 · img2.video prices checked October 24, 2026
Most AI video generators bill monthly whether you render or not. img2.video bills per video: one-time credit packs from $5.90, credits that never expire, no auto-renewal. This page puts the two models side by side with real numbers, so you can see exactly where each one wins.
What subscriptions actually cost (2026)
| Service | Entry plan | Monthly billing | Mid tier | Credit expiry |
|---|---|---|---|---|
| Runway | Standard | $15/mo ($12 annual) | $35/mo (Pro) | Rolls over 1 month |
| Kling AI | Standard | $10/mo list (first month less) | $37/mo (Pro) | 31 days, ends with sub |
| img2.video | Mini pack | $0/mo — pay per pack | $5.90–$89.90 once | Never expires |
Competitor prices from their public pricing pages, October 2026; confirm before purchase. Runway also offers annual billing ($12/$28/$76); Kling shows promotional first-month prices with higher renewal.
Per-clip math: where each model wins
On img2.video, a 5-second clip starts at $1.72 (20 credits at the $9.90 Starter rate) — see the full per-clip cost table. Runway’s Standard plan at $15/month equals ~8.7 clips at that rate; Kling’s $10 Standard equals ~5.8 clips. Generate less than that in a month and the subscription costs more than pay-per-video — every single month.
| Your usage | Subscription (6 months) | One-time credits (6 months) |
|---|---|---|
| 2 clips a month (occasional) | $10–15/mo billed anyway — $60–90 over 6 months | $9.90 Starter pack covers ~5 clips — $9.90 total over 6 months |
| 6 clips a month (hobby) | $60–90 over 6 months, unused credits may expire | ≈ $10.35/mo at Starter rate — $62 over 6 months, nothing expires |
| 20 clips a month (regular) | $60–90 over 6 months — subscription wins on bulk credits | ≈ $34.40/mo at Starter rate — consider Max pack to cut to $27.60/mo |
| One idle month (no renders) | $10–15 billed in full | $0 — balance untouched |
What you give up with packs — honestly
- 📉 Bulk discounts cap out. A $619/month Kling Ultra+ plan pushes per-credit cost below any one-time pack. Studios rendering hundreds of clips a month are better served by subscriptions.
- 🔁 No monthly auto-top-up. You buy packs manually when you run out (the exact remaining balance is always visible).
- 🏷️ Competitor promo pricing exists. First-month discounts make subscriptions look cheaper up front; renewal prices are what the table above uses.
The bottom line
If you generate fewer than ~6 clips a month — which covers most people animating a pet photo, a product shot, or a family keepsake — one-time credits are strictly cheaper, with zero recurring risk. If you render daily at volume, subscriptions win; img2.video is built for everyone in between.
Frequently asked questions
Can I use an AI video generator without a monthly subscription?
Yes. img2.video sells one-time credit packs from $5.90 (60 credits) with no auto-renewal — credits never expire and you only pay when you generate. By contrast, Runway’s cheapest paid plan is $15/month and Kling’s is $10/month (list price), billed whether you render or not.
Is pay-as-you-go cheaper than a subscription?
It depends on volume, and the math is simple: at img2.video’s Starter rate a 5-second clip costs $1.72, so a $9.90 pack covers 5 clips with credits left over. If you generate fewer than ~6 clips a month, one-time credits cost less than the cheapest Runway or Kling plan. Heavy daily users may get more from a subscription’s bulk credits — the crossover is roughly 8–10 clips per month.
Do subscription credits expire?
On Kling, monthly credits are valid for 31 days and expire when the subscription ends. On Runway, unused individual-plan credits roll over for one month. img2.video pack credits never expire — buy once, spend them next week or next year.
What happens in a month when I don’t generate anything?
With one-time credits: you pay nothing and lose nothing — your balance sits untouched. With a subscription: the month still bills in full. Over six months, an idle Runway Standard subscription costs $90 and an idle Kling Standard costs $60 (list), against $0 on pay-per-video.
Which is better for occasional use — packs or plans?
For occasional use (a few clips a month: one product demo, one pet animation, a birthday keepsake), one-time credits win on every axis: lower entry cost ($5.90 vs $10–$15), no recurring charge, no expiry, and automatic refunds for failed renders. Subscriptions only pay off at sustained volume.
